Frequently asked questions
What does ASTM B443 cover?
Covers alloy 625 plate, sheet and strip in two grades: Grade 1 (annealed) for service up to about 593 °C and Grade 2 (solution annealed) for higher-temperature creep service.
Which grades are covered by ASTM B443?
On this site: Inconel 625.
Do you supply material certified to ASTM B443?
Yes. Material is supplied to ASTM B443 with EN 10204 3.1 certificates (3.2 on request), where the mill certifies to it.
Is ASME SAB443 the same as ASTM B443?
ASME adopts many ASTM material specifications into Section II with an "S" prefix (for example SA-443). The adopted text is identical or includes stated modifications, and dual-certified material meets both.
